GUS-QS0B-03-1621-DB Description

The GUS-QS0B-03-1621-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 1.62KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable PCB mounting. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital circuits.
